The domain is the set of all possible x values which will make the function work and will output real y values. Square functions and absolute value functions have a domain of all real numbers and a range of y 0. Interval notation and set notation.
The domain of a function is the complete set of possible values of the independent variable. In plain english this definition means. The domain is all the values that x is allowed to take on.
